Welcome to GMAT

The General Mission Analysis Tool (GMAT) is an open-source space mission analysis and design tool being developed by a team made up of NASA, private industry, and a range of academic, public, and private contributors. GMAT is intended both for real-world engineering design studies and as a tool for education and public engagement in the spirit of the NASA Charter.

This wiki contains many resources for GMAT users and developers. It is intended for collaboration! If you see anything wrong with any of the pages on this wiki, or wish to add GMAT-related information on your own, please feel free to contribute.

The GMAT development team is pleased to announce the release of GMAT version R2016a. The General Mission Analysis Tool (GMAT) is the world’s only enterprise, multi-mission, open source software system for space mission design, optimization, and navigation. The system supports missions in flight regimes ranging from low Earth orbit to lunar, libration point, and deep space missions. GMAT is developed by a team of NASA, private industry, public, and private contributors and is used for real-world mission support, engineering studies, as a tool for education, and public engagement.

For a complete list of new features, compatibility changes, and bug fixes, see the Release Notes. Below are just some of the new capabilities contained in this release.

GMAT Users, we’re happy to announce production quality console releases on Mac and Linux. (Note the GUI is still Beta on those platforms.)

Here’s more info from the release notes: This release of GMAT introduces production quality builds of the core GMAT system for Mac and Linux workstations. THE COMMAND LINE GMAT APPLICATION HAS BEEN TESTED EXTENSIVELY using GMAT's script based test system, and is now certified as fully functional. THE GUI INTERFACE FOR MAC AND LINUX USERS HAS NOT UNDERGONE RIGOROUS TESTING, AND SHOULD BE CONSIDERED AS A BETA INTERFACE INTO GMAT FOR MAC AND LINUX USERS. Additional notes can be found below for the Mac and Linux release packages.

GMAT R2015a is our best work yet and is a major, feature-rich release. For a complete list of new features, compatibility changes, and bug fixes, see the Release Notes. Below are just some of the new capabilities contained in this release.

The General Mission Analysis Tool (GMAT) team is pleased to announce that we are holding our introductory "GMAT Fundamentals" training course at NASA Goddard Space Flight Center in Greenbelt, MD, on October 29th.

This training will cover an introduction to the GMAT project, key features, mission examples, current status, and a series of guided introductory tutorials covering simple propagation, orbit transfers, B-plane targeting, finite burn targeting, and multiple-shooting optimization. GMAT is a general-purpose trajectory simulation and design tool for desktop use, co-developed by NASA and commercial partners. You can find out more information at http://gmatcentral.org.

This is a full 8-hour live course hosted at GSFC. We are happy to facilitate public attendees via web conferencing. Web attendees will be able to interactively participate in all portions of the training program.

Please note that this specific training event is for US Citizens only.

If you are interested in this training, please contact Jason Laing at jason.t.laing@nasa.gov. We will contact all respondents with further details.

The GMAT team was excited to attend the AIAA SPACE 2014 conference in San Diego earlier this month. We presented two papers covering the QA and flight qualification efforts that took the better part of two years, ending last August.

Do you want to go to Mars but don't know when to leave or how much to bring? Do you want to study Earth protection by planning a mission to a near-Earth asteroid? Do you want to place a telescope in an orbit that is always looking outwards from the Earth and Sun? The General Mission Analysis Tool (GMAT) is an open-source space mission design tool to help you answer these and many other space flight challenges. GMAT is developed by a team of NASA, private industry, and public and private contributors. It is used for real-world engineering studies, as a tool for education and public engagement, and to fly operational spacecraft. You can download GMAT here: Windows Installer , Source Code.
